Additionally, in wake up and sleep mode, digital 3D Hall sensors similar to the TMAG5273 can be configured to generate an interrupt once a certain threshold is crossed. This process is particularly useful in cases, where the user interfaces like buttons or triggers are used to wake up the system. A device like TMAG5273 can be placed in wake up and sleep mode, where the sensor wakes up after a preconfigured sleep time interval, takes a measurement and goes back to sleep. If the measurement crosses a set threshold, the interrupt condition is met. The device can proceed to exit wake and sleep (W&S) mode and can go to stand-by mode as shown in Figure 2-5.
